Reproductive Activities

The using of palm oil waste had not been optimal lately. It could be seen in oil empty fruit bunches (EFB). It was placed along the oil palm plantations. The condition was not only the trigger of air pollution but also could invite rhinoceros beetle pests (Oryctes rhinoceros) to lay their eggs and carry out reproductive activities due to availability organic matter of the trees. Oil palm plants required large amounts of macro nutrients, especially potassium. However, the potassium nutrient was found in EFB was too slow available because of its relatively long breakdown. That was the reason why it was needed a method of using EFB waste into a capable of high use value product, environmentally friendly, and could give a lot of benefits to oil palm farmers. The purpose of this study was to determine the availability of nutrient content in EFB composting by the using of symbiont bacteria from larvae O. rhinoceros. The research was experimentally conducted a factorial randomized block design (RBD) with 2 factors, namely the type of bacteria and the time of decomposition. The composting stage was carried out by coarsely chopping the EFB then 75 ml of bacterial culture was applied to 1 kg of EFB. Analysis, results indicated C/N ratio (35.56% and 36.97%) and high K content (1.64% and 1.48%). The EFB composting method is achievable in 6 weeks with activators of Bacillus stratosphericus and Bacillus siamensis.

Leachate Quality

The problem encountered in acid sulphate soil is the presence of pyrite (FeS2) which causes soil  to have highly acid reaction when the pyrite is oxidized. The decline in quality not only occurs on the soil  but also on the quality of the surrounding waters. One way to improve the quality of the leachate is by draining it through biofilter plants in the form of purun tikus (Eleocharis dulcis) and bulu babi (Eleocharis retroflaxa) which can absorb or neutralize these elements. The purpose of this research was to know the inoculant influence of iron oxidizing bacteria to leachate quality in acid sulphate soil. The research was conducted on a pot scale in greenhouse. The research was in randomized block design (RBD) of 3-factors with 3 replications. The first factor was inoculants, the second factor was water management, and the third one was phytoremediation material (Eleocharis dulcis  and Eleocharis retroflaxa). The results showed that the plant height in the inoculant treatment+wood charcoal was in the range of 89.33−95.33 cm, while that in the inoculant treatment+husk charcoal was in the range of 89.50­­­−93.00 cm. Meanwhile, the yield of rice with bacteria oxidizing iron inoculant+wood charcoal was higher, which was at 6.77 ton.ha-1 than inoculant treatment of oxidizing iron+husk charcoal which was only 5.95 ton.ha-1.

<p><span style="font-size: small;"><span>Making acid sulphate soils as paddy fields is a wise choice because it can prevent the soil from oxidizing which occurs in acidification of the soil. The use of biochar as an amendment to the land has long been known since the discovery of terra preta since 1870 in the Amazon Basin as the Amazon dark earth. Because biochar soil amendments are rich in C-organics, have a buffering capacity and can increase soil acidity, are able to absorb heavy metals, and are able to retain water and nutrients for soil organisms. Meanwhile, lime has also been known as an acid sulphate soil amendment in Rome 2000 years ago to balance the acidity in agricultural land. This has been practiced for centuries until now. Though compost or organic soil can be traced more than 2000 years ago. Soil organic matter (SOM) is formed from the remains of animals and plants. It contains C and many nutrients such as N, P, and K. Based on the description above, the author wants to combine the three ingredients in the review, especially in relation to acid sulphate soils.</span></span></p>

Winged bean (Fabaceae) is a tropical crop that has high nutrient content, and almost all parts of the plant are edible. The research aimed to evaluate the growth and production of winged bean in an intercropping system with tomato. The study was conducted at the Cikabayan Experimental Field of Bogor Agricultural University, Bogor, Indonesia, in a randomized block design with three replications during the rainy season of December 2017 to June 2018. Winged beans were planted in high and low population densities and intercropped with three tomato genotypes, “Tora”, F70030081-12-16-3 and “Apel Belgia”. Monoculture winged bean was assigned as control. Tomatoes were planted between the rows of the winged beans in the intercropping treatment. The results showed that the growth of winged bean in monoculture and intercropping systems was not significantly different. The photosynthetic activity of winged bean at three to five weeks after planting remained high, indicating that the vegetative growth was optimal in both systems. Intercropping increased the winged bean number of pods per plant by 12.66-19.52% compared to monoculture, irrespective of population density. Therefore, winged bean could be considered as suitable to grow in intercropping systems.
